Selenium，Python：如何在iframe中单击？

Question

我认为没有必要进一步扩大我的问题，一切已经很清楚了。我想做的是单击按钮以通过音频解析验证码，但是硒无法检测到指定的“ id”。

browser.get("https://www.google.com/recaptcha/api2/demo")
    mainWin = browser.current_window_handle  

    iframe = browser.find_elements_by_tag_name("iframe")[0]
    browser.switch_to_frame(iframe)

    CheckBox = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.ID ,"recaptcha-anchor"))).click()
    sleep(4)

    audio = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.ID ,"recaptcha-audio-button"))).click()

Answer 1

您可以在切换到frame_to_be_available_and_switch_to_it之前尝试等待条件iframe：

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC


wait = WebDriverWait(browser, 10)
wait.until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//div[@id='recaptcha-demo']/div/div/iframe")))

CheckBox = wait.until(EC.presence_of_element_located((By.ID ,"recaptcha-anchor"))).click()
sleep(4)

audio = wait.until(EC.presence_of_element_located((By.ID ,"recaptcha-audio-button"))).click()
